11g R2 RAC: ADD BACK DELETED NODE

In 11g R2 RAC, when a node is deleted, only the OCR and the inventory of the remaining nodes is updated. Grid software from the deleted node is not removed and inventory of the deleted node is not updated

(/u01/app/oraInventory/ContentsXML/inventory.xml)

Hence, to add back a deleted node we need not copy the Grid software on the node which was deleted earlier. Only the following steps need to be executed:

Current scenario:

I have two nodes in the cluster presently.

Host names :

- host01.example.com

- host02.example.com

Node which was deleted earlier and has to be added back:

- host03.example.com

———————————————————-

– Run addNode.sh from a currently existing node (say host01) with no copy option
